Ford Ranger / B-Series :: Engine Starts To Race Without Coming Back To Idle
Feb 23, 2012
2000, 2.5L standard transmission. IAC replaced about 2 years ago, DPFE sensor and vacuum hoses replaced early last summer. Truck has been running just fine until I washed it last night. Went to work, and when coming to a stop and pressing in the clutch, engine starts to race without coming back to idle. Had to turn the truck off in order to get the engine from racing. Same thing on the way home. What else can/should I be looking at? I did not open the hood to wash the engine off, so it can't be water from the wash.

My 3.0 with 216k miles has developed a rough idle and it progressively got better with new parts and cleanings. On startup it revs up to 2k then back down to 600. If I let it idle for about 8 or so minutes my Check Engine Light starts flashing. If I drive about for a little bit it stops and is just fine.
While the light is flashing I get codes P1000, P0305, P0306, and P0316. Which are OBDII Monitor Testing Not Complete, Misfire detected in Cyl 5, Misfire detected in Cyl 6 and Engine Misfire Detected on Startup (First 1000 Revolutions) respectively. Any other time the truck runs like a dream. Gets 20 city and 29.5 highway.
I cleaned my Mass Air Flow, replaced my Idle Air Control, SeaFoamed throttle body and vacuum lines, brand new coil pack, new wires, new plugs, new fuel filter, I've only ever run 91 octane, Chevron with Techron goes in at every oil change and B12 every other and I just ran 3 bottles of Lucas fuel injector cleaner.

Got a 1986 Ranger 2.3 EFI 5 speed that I have owned since it was almost new and will never let it go. 290,000 mls and still running strong "except". Noticed the last couple of months that when I start it cold it fires right off. If I start it hot it always takes 3 tries and always goes on the third try except....on occasion it will not start at all. It is random and after I let it cool a bit (about 30 min) it will start. Over the years I have replace many of the fuel system components (fuel tank pump, high press. pump, inline filter and canister filter, fuel press regulator) but wondering what else might be the problem.
I put a pressure tester on it the other day and when I selected the key to start the pump would spool up to build pressure and shut off. The press gauge would register that but the pressure would immediately go back to zero. After start up it would hold a constant 30psi at all rpm,s. Shut the engine off and pressure drops right down to zero. Shouldn't the system hold pressure for at least a while after shut down? Could this be the problem with my sluggish starts? What would be the normal fuel pressure? Can't seem to find it in my Haynes manual. Once running it runs great.

88 ranger. 2.9L manual. Just bought this truck. It ran great when I bought it. After a day or 2 it would idle rough. Almost die but it wouldn't. No check engine light. It seemed to do this intermittently. Some times I'd start it and it be fine. Other times I'd start it and I'd expect it to die at each stop light.
Now for the last couple days it dies on every start up. It won't idle. It'll start right away and then die. I can keep it going by keeping the engine rev'd but the check engine light is one. If I keep it running and start driving down the road it'll drive with the check engine light on for about 5 minutes. Then the light goes out and it runs like normal, even at idle, until I shut it off. Then it's the same story at next start whether it's right after I shut it off or hours later.
It doesn't seem to matter whether the engine is hot or cold. When the check engine light is out, it runs great the rest of the time whether at speed or at idle. To me it sounds like a sensor is on it way out. I figure if it was vacuum, it happen at every idle, and if it was fuel it happen all the time or at least every idle. Tried to get a code at parts store but the reader wouldn't work. It couldn't tell it was plugged in the the truck for some reason.

I've got an issue with my 92 2.3 ranger.... sitting at idle for 30 or so seconds it starts to chug and sometimes dies.... I can hit the throttle and its fine for another 30 or so seconds.... while cruising on the freeway after about 30 minutes it starts to cut out badly... let out of throttle for a few seconds and it clears up and drives fine...
Here's the part that has me confused... pulled codes yesterday using a innova scan tool...
koeo were 4, 10, and 538...
koer were 111, 10, 157, 158, 181, 327, 328, and 334....
How does it give me a 111 pass code and then still come up with all the other codes? I am thinking my ecu may be screwed.....

Which one is the ect? One is the ect and one is a switch for something?
Just gone done switching that POS plastic thermostat housing thing, both sensors were replaced not sure which one is throwing the code.
I have cleared the code and it keeps coming back.

1991 2.3L 5 speed .... Okay here's my list of issues.... At idle will stall out, its almost as if i shut the key off, or sometimes taking off it'll sputter and stall, fuel filter has been changed. Back part of the tranny housing leaks, is there a gasket for that?

My truck has been doing this since I got it and I can't figure it out. It's a 2000 Ford Ranger XLT 2.5 5Spd. It runs fine if you don't rev it above 2500-3000 rpm. After you rev it that high coming down to idle it is stumbling real bad and sometimes stalls. I've been driving it like this since I got it, and it does fine other than this. It gets better the longer you drive it, but it still will do it if you rev it high enough.
Here are all the parts I personally have changed (previous owner said he did the plugs and wires and air filter, which it looks like he did but I'm about ready to change them myself):
-Fuel filter
-coil packs
-timing belt
-egr valve
-cleaned throttle body
-iacv
-tps
-thermostat

My surging/running down issue has returned on my '86 2.3l Ranger. I thought it was electrical, when things improved with the new ignition switch, but lately it's hard to get out of 2nd gear before the engine surges then starts to lose power. a poke of the gas pedal starts the who cycle over again. I pulled codes but it's hard to tell what the reader is saying either 33 and 34 or 334. The good thing is all the codes point to the EGR system. Looking for a diagnosis tree to determine if the valve is bad or the sensor is shot? They are both not cheap so I don't want to just throw parts at the problem.

I have a '92 Ranger with a 2.3 liter engine. She starts and runs a couple of seconds and shuts down. I'm thinking maybe a fuel pump is not putting out thepressure needed. Gotta go to work tomorrow and gotta get the truck running today.

'02 Ranger XLT, extended cab, 4X4, 4.0L SOHC, 5-speed manual, 114K miles.
Problem has occurred twice. After extended run time and engine fully heated, when I get home and shut it down, then attempt to restart within a short period of time, the engine starts very briefly, then begins shuddering violently and dies within a few seconds. Re-attempts to start result in a very shuddering attempt to run for a couple seconds, and then it dies. After a couple of re-attempts, it doesn't even attempt to start; just cranks over with no results. Has to sit about 7-8 hours before it will restart.
No OBD II codes; Passed, no codes shown. I purchased a crank position sensor, but haven't installed it yet: just a stab in the dark after hearing other people's experiences with other vehicles.
First occurrence followed a lengthy trip in heavy stop-and-go traffic. Shut it down when I got home, then attempted to re-start after a few minutes to run a short errand. Sat for two days without any re-attempts; then restarted and ran fine on first try a couple days later.
Second occurrence followed a couple hours of hitting yard sales with the neighbor, in which time I did not shut the truck down; just left it idling while we perused the sales, for fear it wouldn't re-start. Reckon it's a good thing I did, 'cause when we got home and I shut it down and attempted to leave again shortly thereafter, it malfunctioned as described.
Retries failed after sitting 4-5 hours, but after eleven hours of sitting, it started right up and ran normally.

96 Ranger x cab 4.0 ltr automatic... Starts fine, runs fine until I stop.
When I stop, the engine idles oddly - it slows and speeds back up, tachometer and the battery gauges both lower just a bit and immediately return to normal. When the headlights are on, they dim in rhythm when the gauges dip. It does not do this in park or neutral.
Sometimes it does it right away. Sometimes it doesn't do this at all. Of course it did not do this when I took it to the shop. The battery is nearly new. Cables are fine. Alternator checked out ok.

I have a 3.0 Ranger, AT 2WD, from 2001 with 175K miles on it. I have a CEL on, with Misfire cylinder #5.
Also when the truck is cold and I step on the gas, it seems to run on like 3 cylinder for 2-3seconds and then it somehow fixes itself and runs great until it warms up.
After it warms up, it shakes violently at idle. The shaking goes completely away once I'm past 1200 rpm or while driving. What I tried so far:
- All new Motorcraft filters (Air, fuel)
- Motorcraft Plugs
- Motorcraft Wires
- Motorcraft Coil
- Ran thru two cans of SeaFoam
- Checked injector resistance
- "Reset" the ECU
- Cleaned MAF sensor
- Cleaned IAC
What else I need to check?

So i have a 2000 ford ranger 2wd 4cyl .190k miles. My issue is the motor has a very rough/shaking idle,abs light on,and check engine light on.it also continues to blow fuses to the tail lights and dash, haha
Ive had it since it was at 40k and has been a great truck,although lately i have really neglected it.ive changed the spark plugs and new wires new timing chain. I would d love to start trouble shooting some of this stuff this weekend if the weather holds up.

I have a 1999 B4000 4.0L with 160K miles on it. Bought the truck new. Up until about a year ago it ran perfect but has developed an idle, stalling and occassional jerky ride problem. It occurs at any temperature, engine hot or cold, A/C clutch on or off and in Park, Drive or Neutral. When you start the engine it will not idle unless you keep your foot on the gas. The idle speed will drop to 200-300 rpm and the engine dies. Sometimes you can barely tap the gas pedal and the rpm will shoot up to normal idle speed (about 900 rpm) and stay there a few seconds then begin to drop again. If the engine is cold it will often die a couple times after starting even with the foot on the gas and then about the 2nd or 3rd time run with your foot on the gas.
At stop signs and red lights you have to keep your foot on the gas to keep it running. If you are approaching a stop sign and take your foot off the gas to coast to a stop and brake, the engine rpm will drop and the engine will die. It always starts fine though. Once you are driving it generally runs just fine at low or high speed. You can generally set the cruise control on the expressway and cruise right on. However, sometimes all of a sudden the truck will start bucking and jumping as if it has a terrible misfire. It usually lasts a few seconds and quits. Often if you step on the gas it quits. Even less occasionally the engine will begin to slow as if it is starved for fuel and slow down. You can press the pedal to the floor and it sputters a bit then picks up and runs fine.
I have read about all the threads in this forum and others and tried some of the suggested fixes but it still has the problem. I have tuned it up with new plugs, wires, fuel filter, air filter and PCV valve. Based on some of the forums advice I have replaced the IAC valve, the EGR valve and EGR Pressure Feedback Sensor, and cleaned and inspected the MAF sensor with MAF cleaner. I have checked all my vacuum lines and no leaks there and checked the engine timing which is fine. Fuel rail pressure and engine compression are also fine. Spark plugs show no clues, exhaust is clean and the engine uses virtually no oil. There has been no tear down on the engine like removing the heads, cam, timing gears or any of that and the engine is completely stock.
It shows no codes related to the problem. Two or three months after the problem started I showed a code that indicated an injector problem, traced the problem to a bad injector, replaced the faulty injector and it was fine. That took care of that code but didn't solve the idle problem. In my younger days I was into drag racing and I rebuilt engines, swapped transmissions, etc. and still do my own tune-ups today so I am fairly familiar with auto repair and have most of the tools for testing newer cars but this one stumps me. As a last resort I'm about to take it to the dealer.

Ive got a '94 ranger with the 8 plugs and more often than not while driving and sometimes when it first starts, the cel comes on and immediately I notice a lil rough running and lack of power. Also my milage has dropped since this has started. Plugs, wires, o2 sensors, not to familiar with my gas saver. I love it cause I can just get in it and go. With twice the fuel milage as my bi truck!

Changed my oil today. Noticed oil coming off the front of the engine. Where this could be originating or do I need to take the belt cover off? I hate having a leak. Wanna get it to stop. Just need to know what I may be up against. 1996 2.3ltr.....

I’ve got a 1998 Ranger with 166,000 miles and it’s starting this weird idle at stops where the engine drops about 150 RPM’s and then fluctuates. The problem is intermittent and no pattern as to cold or warm engine. I changed the plugs and wires at 100,000 and the plugs again at 150,000, so the wires have 66,000 and the plugs 16,000. I really don't want to shotgun the plugs, wires and coil pack. I understand that vacuum might have something to do with my problem?

I have a 1998 ranger 2.5L engine. I took it to a Ford garage and they told me I have a rod knock..........I took it also to a good mechanic and he said the sound is coming from the lifters.
There is 172000 miles on motor and the noise started at 131000, and is getting worse. Should I drive it till it blows, or is there a way to tell what the problem is?

1996 Ranger 2.3 140 CID XLT 126,000 Miles. When coming to a stoplight or stopping the engine idle is low and causing engine to almost die. Engine has been stuck at high idle a couple of times. It started with the engine idle slowly coming down and now it its too low. I suspect the Idle air control valve.
